+#### Security Improvements
+
+This release fixes two security CVEs by updating dependency versions.
+
+* {% jira 2610 %} Update log4J dependency to fix CVE-2021-44228
+* {% jira 2611 %} Update JDOM dependency to fix CVE-2021-33813
+
+#### Functional Improvements
+
+A major feature, layering transforms with checksum/CRC capability, which was planned for the prior release (3.2.0) was found to be buggy when unparsing. 
+This has been fixed. 
+
+* {% jira 2608 %} PCAP fails with Daf 3.2.0 and IPv4 layers with checksum
+
+#### Miscellaneous Changes
+
+* {% jira 2577 %} remove Info message about compiler component counts
+* {% jira 2145 %} Add scalac warnings
+* {% jira 2592 %} Move the daffodil_program_version variable outside of generated_code.c
+* {% jira 2534 %} Update ICU version - verify Daffodil impact of bug issue identified by IBM
+* {% jira 2587 %} dfdlx:lookAhead compiler error if used in default value of dfdl:newVariableInstance
+* {% jira 2600 %} encoding varies with environment - UTF-8 not properly set somewhere
+* {% jira 2602 %} Daffodil uses different versions of log4j-api and log4j-core
+
